Concept-Level Sentiment in Projects

Daylight Cloud users have access to Concept-Level Sentiment on July 25, 2020. To access

...

Concept-Level Sentiment is calculated after the core Daylight build. Since the time it takes Sentiment to build depends on dataset size, it may take several hours to complete large datasets. While Sentiment is building, you can’t access the Sentiment feature, though you can explore all other Daylight features. 

To view Concept-Level Sentiment in an existing Daylight project

1. Open the project you wish to rebuild with Concept-Level Sentiment. The project opens to the Highlights feature.

2. Check to see if the project uses Document-Level Sentiment. If it does, you see a banner at the top of the page asking you to upgrade.
   

   

3. Click Upgrade science on the Project details card on the Highlights page. A confirmation window appears, notifying you that your project will be rebuilt with upgraded science.
   

   

4. Click Upgrade. Your project begins to upgrade.
   Note: Because Sentiment in Daylight is calculated after the core build is done, you may have to wait to access the Sentiment feature after the rest of the build.

To use the Concept-Level Sentiment Feature

1. Open a fully built project that uses Concept-Level Sentiment. The Highlights feature opens. 

2. Take a look at the What concepts do people feel strongly about? card to view initial concept sentiment suggestions.
   Note: Because sentiment suggestions prioritize sentiment is strong and has high confidence scores, this card will display very negative suggestions. 

3. Open Sentiment by clicking Sentiment feature on the What concepts do people feel strongly about? card in Highlights or the Sentiment icon. The Sentiment feature opens. By default, the visualization displays sentiment suggestions, which are concepts that Daylight has identified as having especially strong sentiment. 
   

   

   Note: Because sentiment suggestion concepts are prioritized by strong sentiment, they may appear polarized and usually include very little neutral sentiment. 

4. Use the arrows at the top of the concept list to sort concepts alphabetically, by number of exact matches, percent negative, or percent positive. 

5. Change the concepts displayed in the concept list using the options in Configure sentiment visualization. 

6. Click on an interesting concept to view examples of how the concept is used in contexts with negative, positive, and neutral sentiment.

   

   Note: If Daylight can't confidently determine that a concept was used in a positive, negative, or neutral context, it does not display a corresponding example.

To conduct deeper analysis in spreadsheet exports

1. Apply filters as desired. 

2. Select a concept and click Download more matches to explore more matching documents. A spreadsheet downloads with documents based on:

   • The specific concept(s) you have selected

   • The filters you have selected.

   • The type of concept you have selected – Top concepts, Sentiment suggestions, or Saved concepts

3. Open the spreadsheet. It opens automatically to the Sentiment distribution tab. 

4. Use the Sentiment distribution tab to: 

   • Browse sentiment information for the total product

   • Skim sentiment information using color-coded concepts

   • View sentiment information for all concepts included in your filter

5. Use the Sentiment documents tab to view all documents that were included in your filter, and their associated sentiment information.  

Other major Daylight updates 

Some Concept-Level Sentiment changes occur outside the Sentiment feature: 

• Project management – Now, the Sentiment feature builds after the rest of the Daylight project. Optionally, receive emails that notify you when Sentiment is done calculating.  

• Highlights card – The What concepts do people feel strongly about? card now displays information about concepts, not documents, that communicate strong sentiment. 

• Update to build emails – Now, build emails reflect the build status for your overall project and for the sentiment feature. 

• Sentiment export – Now, if a search is applied at the time of download, the Sentiment export contains two tabs. T he second tab contains Sentiment Documents,
  Sentiment export – Advanced concepts are now included in the sentiment export. THe export represents the same document in multiple rows so that each concept-document pair displays correct sentiment. 

• Download Documents – The Download Documents export no longer displays sentiment information, since sentiment is now calculated on a concept-document pair basis, and not document- level basis. 

• Concept details pane – Now, there is no option to select Sentiment documentsin the Documents section of the Concept details pane, since Daylight no longer calculates sentiment on the document level.
